Question About My Player and Online TeamUp

[baseballredsox]

I haven't started My Career yet but I still made My Player. How do I change his position/height etc? I want him to be a Center but can't find the option anywhere.

Also, I've recently dived into playing online and have played two matches in online team-up, which is actually fun (except for all the ball hogs). I like playing as big men and I understand that everything is chosen at random, but both times I've been designated as the PF (not complaining, just would like to try out a PG). I'm worried that my My Player may be a PF and that's why I've only been assigned to them?

Help me out please, sorry I'm a bit of a rookie.

You don't set your height, position, ect. Until you begin your career. It's the first thing you do. Online team up has nothing to do with my player.
